Embodiment 1

[0012] Rosin improved phenolic resin: take 2100 parts of p-octylphenol to dissolve, add 90 parts of 25% caustic soda solution, 160 parts of 37% formaldehyde, and react at 55°C for 8 hours to obtain the initial condensation product of phenolic resin; take 750 parts of rosin, Malay 30 parts of acid anhydride and 250 parts of initial condensate of phenolic resin were placed in a reactor, under the protection of nitrogen flow, stirred and reacted at 180-200°C for 3 hours, then added 106 parts of pentaerythritol and 16 parts of glycerin, and reacted at 200-270°C until acid When the value reaches 15-20, the rosin-improved phenolic resin is obtained.

[0013] Modified alkyd resin: take 70 parts of linseed oil and 11.5 parts of glycerin for transesterification, then add 24.6 parts of isophthalic acid for esterification to obtain the product.

[0014] Alcohol-based resin coating: Take 9 parts of rosin modified phenolic resin, 7 parts of modified alkyd resin, 7 parts of kaolin, 10 parts...

Embodiment 2

[0016] Alcohol-based resin coating: Take 8 parts of rosin modified phenolic resin, 6 parts of modified alkyd resin, 5 parts of sodium carbonate, 8 parts of pigment, 0.5 part of dispersant, and 65 parts of ethanol. First heat and dissolve rosin-modified phenolic resin and modified alkyd resin in ethanol, then add other components in sequence, and use a grinder to disperse the system evenly, and the particle size should be below 10 μm.

Embodiment 3

[0018] Alcohol-based resin coating: 10 parts of rosin modified phenolic resin, 8 parts of modified alkyd resin, 8 parts of barium sulfate, 12 parts of pigment, 0.7 part of dispersant, 55 parts of n-butanol. First heat and dissolve rosin-modified phenolic resin and modified alkyd resin in n-butanol, then add other components in sequence, and use a grinder to disperse the system evenly, and the particle size should be below 10 μm.

Abstract

The invention discloses a composite resin coating. The composite resin coating comprises the following components in parts by weight: 8-10 parts of rosin modified phenol resin, 6-8 parts of modified alkyd resin, 5-8 parts of filler, 8-12 parts of pigment, 0.5-0.7 part of dispersing agent and 55-65 parts of solvent. The resin coating prepared according to the invention has the advantages of better resistance to emulsification, stability, fixation and dryness, as well as stronger wettability and color emissivity to the pigment.

Description

technical field [0001] The invention relates to a resin coating, in particular to a composite resin coating for ink. Background technique [0002] Printing ink is a fine chemical product that transmits information and decorates the cultural world. Both the ink industry and the printing industry develop with the prosperity of the national economy and the development of cultural and educational undertakings. The technical progress and production of ink are to some extent one of the signs of the cultural development of the region. [0003] Traditionally, vegetable oil is used as a binder to prepare inks. With the advancement of industrial technology, various types of resins have gradually replaced vegetable oils and introduced into the field of ink binders. However, most inks currently use toxic benzenes, ketones, ethers, etc. as solvents, which are harmful and affect the environment. Contents of the invention [0004] The object of the present invention is to provide a l...
